Pressu
re on Surface B > Pressure on Surface A
Answer:
Density = 11.294g/cm³
Explanation:
Mass of the ball (m) = 5.910g
Diameter of the ball = 10.0mm
Radius r = 10.0/2 =5.0mm = 0.5cm
Volume of a sphere V = (4pr3)/3
V = 4*3.14*(0.5*0.5*0.5)/3 = V =1.570/3
V = 0.5233cm³
V = 0.5233cm³
Density = mass/volume
Density = 5.910/0.5233
Density = 11.2937g/cm³
Density = 11.294g/cm³
Cooks should use sea salt in recipes instead of regular table salt.
Answer:
the derived unit of speed in m/s as distance/time is speed. Meter as second are the base units from wich it is made of.
The volume of oxygen required to burn 12.00 L ethane is calculated as follows
find the moles of C2H6 used
At STP 1 mole is always = 22.4 L, what about 12.00 L
= ( 12.00L x 1 moles) 22.4 L = 0.536 moles
write the reacting equation
2C2H6+ 7O2 = 4CO2 + 6H2O
by use of mole ratio between C2H6 :O2 which is 2:7 the moles of O2
= 0.536 x7/2= 1.876 moles
again at STP 1mole = 22.4 L what about 1.876 moles
= 22.4 L x 1.876 moles/ 1 mole = 42.02 L
